Thousands of people have been forced to flee the long-besieged city of Fallujah and are at risk of disease and death in sweltering hot camps.

Iraqi pro-government forces, tribesmen and popular mobilisation forces stormed the Iraqi city, which is around 30 miles west of Baghdad, on May 22.

This has sparked a continuous mass exodus of around 84,000 people so far. According to the UN, this number is soon set to rise to around 150,000.

Many of those escaping their homes are children.

The region had fallen to Isis forces and allied jihadist groups two years ago. Now, reports claim Isis are shooting any civilians that they see attempting to leave.

Despite this deathly threat, in the last few days alone tens of thousands of people have fled the city centre and are staying in refugee camps set up by the Government of Iraq and partners.

However, these camps are now all full – leaving thousands of people without anywhere to go.

This comes as the current refugee crisis has been confirmed as the worst in the history of the UN.

Wars in Iraq and neighbouring Syria have pushed the total number of people displaced from their homes to more than 65.3million globally, as of the end of last year.

There is a severe shortage of food, water, medicine and sanitation for those escaping Fallujah. Many of those fleeing don’t even have tents to shelter themselves from the sweltering 48C heat, meaning families are being forced to sleep in the hot, open air.

In an attempt to provide some urgent life-saving assistance for these people, the UN’s Central Emergency Response Fund (CERF) has released £10.2million.

However, there are fears that this is simply not enough.
